The utility model relates to a quantitative adding powder device for a covered sand production line, which relates to a quantitative powder adding device for a sand coated production line of a casting production line equipment. It includes the material box, the bottom is fixed with two open end button box, with the quantitative cavity slide fit in measuring button box measuring end is connected with the piston rod of the cylinder when the cylinder piston rod, push pull gauge slide in the button box when the cavity is a quantitative out to the outside box buckle charging, another is the quantitative cavity button box corresponding to the discharge port of unloading. A through hole is arranged on the top surface of the buckle box to connect with the vertical breather pipe. The two end of the measuring tool is fixedly connected with a broken arch material rack. The utility model has the advantages that the upper surface of the buckle box is provided with a through hole and is connected with an upper opening vertical ventilating pipe, so that the inside of the buckle box and the quantitative cavity are communicated with the atmosphere, and no negative pressure is generated, so that the discharging is pleasant and smooth. And because of the added arch breaking draw frame, the material box arch material no longer appear empty, fast and accurate loading.
【技术实现步骤摘要】
覆膜砂生产线定量加粉料装置
:本技术涉及铸造生产线设备,主要涉及覆膜砂生产线定量加粉料装置。
技术介绍
:覆膜砂生产线用于将普通砂进行覆膜制成覆膜砂,采用的覆膜材料包括树脂、乌洛托品、硬脂酸钙等。粉料硬脂酸钙质轻不便于称量后添加,所以现有技术中不采用称量添加,而是通过所加料体积间接等于添加一定粉料重量,具体方法是制作一套定量加粉料装置,具体讲是通过液压缸推拉一量具,该量具处于二端开口的扣盒内可左右移动,当量具的一个定量腔移动至扣盒外时便向腔内加料时,此时量具的另一个定量腔则处在扣盒内卸料,如此左右移动装料、卸料,或卸料、装料。以上现有加粉料装置存在的缺陷是,一,量具、扣盒处于料箱的粉料之中,定量腔卸料时易出现负压状态,致使卸料落料不痛快流畅。二,箱内粉料易出现支空、打拱现象,影响装料,现缺少一个消除支空、可破拱的机构。
技术实现思路
:本技术的专利技术目的,是提供一种覆膜砂生产线定量加粉料装置,它定量准确,使用方便,定量加粉料效果好。本技术的技术方案是,覆膜砂生产线定量加粉料装置,包括上开口的盛料箱1、与盛料箱箱内底面固定的二端开口的扣盒2、具有定量腔的量具5滑动配合的处于扣盒内2内、量具一端连接气缸活塞杆11,当气缸活塞杆推拉量具在扣盒内左右滑动时,量具的一个定量腔7被拉出至扣盒外进行装料,另一个定量腔6则处于扣盒内对应箱底卸料口9卸料。与箱底卸料口9相对应、于扣盒顶面设有通孔3,通孔衔接有上开口竖向通气管4。量具二端固接有破拱划料架13。所述破拱划料架包括固定于量具二端的立杆、二立杆顶端固接有前后多支纵向横杆13′、每支横杆上焊接有一排多支向下的划料齿14。本 ...
